BOTTLE-NECK CLOSURE.

Specification of Letters Patent.

Patented Oct. 1'7, 1905.

To (.LZZ whom it may concern.-

Be it known that I, EDWARD C. SIIILLING, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Bottle-Neck Closures, of which the following is a specification.

My invention relates to a new and useful improvement in bottle-neck closures.

The object of the invention is to provide a superior guard and valve construction which when applied to the neck, which is specially formed for the reception of the same, produces what is known in the art as a non-refillable-bottle closure.

Finally, the object of the invention is to produce a device of the character described that will be strong, durable, and efficient and simple and comparatively inexpensive to make, and one in which the several parts will not be liable to get out of working order.

With the above and other objects in view the invention consists of the novel details of construction and operation, a preferable embodiment of which is described in the specification and illustrated in the drawings, wherein Figure 1 is a vertical sectional view through the upper part of the bottle, showing the guard and valve in elevation. Fig. 2 is a transverse sectional view taken on the line 90 :10 of Fig. 1, showing the bottle broken away. Fig. 2 is a plan view of the upper portion of the bottle, showing the ribs and offsets. Fig. 3 is a plan view of the guard. Fig. 4 is an inverted elevation of the guard. Fig. 5 is a detail side elevation of the valve. Fig. 6 is a longitudinal sectional view of the valve. Fig. 7 is a detail top plan view of the valveseat, and Fig. 8 is a detail bottom plan view of the valve-seat.

In the drawings the numeral 1 designates the neck of the bottle, which is formed with internal shouldered ribs 2, alternately disposed between recessed oifsets 3, having angular shoulders 4. A guard disk 5 is formed with a fluted head 6 and the contracted ring like portion 7. Oppositelydrilled parallel openings 8 in the ring portion 7 contain coiled springs 99, which impinge pins 10, sliding in the openings and project ing beyond the fluted head 6. When the guard is placed in the bottle, the fluted head the inclined surfaces presented by the ribs 2 and offsets 3,'whereby it is securely held in place. The valve-seat 11 is formed with a plurality of suitable openings 14 and 15, extending therethrough, and with a downwardly-extending hollow stem 16, through which passes the hollow stem 17 of the valve 18. The valve 18 is formed upon its inner or under side with a flat surface 18. A grooved ring 19, formed upon the valve-seat 11, so as to lie about the stem 17 of the valve, holds in place over the openings 14 a flexible valvedisk 20, which normally covers said openings. The valve 18 is formed with a down wardly-extending annular flange 21, which fits around the seat 11 when the valve is in its lowermost position. The upward movement of the valve is limited by a pin 22, which passes through the stem 17 and impinges the lower end of the stem 16. Ports 23, formed in the stem 17 near the valve 18, admit air, which is conveyed by said stem into the bottle. It will be readily seen that when the valve 18 is down the ports 23 are covered by the side walls of the stem 16 and that the valve 18 and flange 21 completely surrounding and covering the disk 20 and the upper portion of the valve-seat 11 it will be impossible to force liquid from the outside through the openings 14 and 15 into the bottle, nor would it in such a position be possible to gain access to the interior of the bottle through the ports 23 and the stem 17.

The parts being constructed as described are secured in the bottle, the valve construction being first put into place and then the guard being placed and securely locked it is impossible to extract them from the bottleneck, as when once the pins 10 have been forced by the springs 9 under the shoulders 4 it will be impossible to press them back and remove the guard. When the bottle is inverted, the valve 18 and its stem 17 are car ried forward until the pin 22 impinges the stem 16, as shown in Figs. 5 and 6. The air passing through the fluted head 6 of the guard and around the flange 21 of the valve '18 enters the ports 23 and travels through the tube 17, thus allowing the liquid to pass through the openings and 14 and by its pressure raising the valve-disk and flowing out around the flange 21 through the fluted head 6 of the guard and out of the neck of the bottle. It will be readily seen that it is impossible to again refill the bottle, as any liquid forced in past the fluted head 6 would act against the valve-head 18 and force the same back to its normal position, thus closing the openings 14 and 15 and the ports 23.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a bottle-closure, the combination with a suitably-formed neck, and a guard locked in position in the neck, of a valve-seat supported in the neck below the guard and 25 having a plurality of openings therein, a flexible washer carried by the seat for normally closing the openings, and a valve slidably\ mounted upon the valve-seat provided with a flat inner surface lying substantially par-15o allel with the valve-seat and adapted to cover the washer and assist in seating the same. 2. The combination with a bottle-neck and a guard locked therein, of a valve-seat frictionally held in the neck below the guard, said valve-seat being formed with a liquid opening and a tubular extension, a disk valve mounted on the seat and normally closing the liquid-opening, a valve having a hollow stem provided with air-ports closing over the said seat and disk valve and having its stem sliding in the said tubular extension.
